Our Scribes have been working…

Monks in scriptorium
We have a couple of long reviews, too long for posts anyway. One’s on paleoanthropology (about our ancestors who came before homo sapiens) and the other is on artificial intelligence. Check them out — Cafe Neandertal  or Superintelligence.

No more having to unwind a long scroll and then rewind it back. Furthermore, the pages were flat, never rolled up, so you could paint gorgeous colored illuminations on the page. It was wonderful. What will they think of next!
